‘From our perspective, the Walder Wyss Public Law team is an obvious market leader. We are not aware of any other law firm that offers advisory and litigation services in public economic law with the same breadth and, in particular, the same quality. Apart from the outstanding legal expertise of over 10 team members, we particularly value their litigation and negotiation skills as well as their in-depth knowledge of our business including political implications. They consistently surprise us with innovative, unconventional ideas (which is exactly the type of innovation we are looking for). The quality of the work is evidenced by the fact that they usually win our cases in court.’
‘The team is very well-rounded and consists of many talented individuals at various levels of seniority. We have had the pleasure to work with many of them.
